Building a Bigger Milling Machine

My small (7" by 7") milling machine just isn't big enough...so I'm using it to build a bigger machine.  If I did this right, the link below should take you to the photo album.  The machine still needs lots of work: 

• beefing up the supports
• adding a strong base
• strengthening the horizontal piece
• adding stepper motors
• adding two stop switches per axis
• adding emergency stop switch
• hooking up all the electronics
